❝ not only ... but also 是各類英文測驗中最常考到的相關連接詞，而測試重點一般都在看考生是否能確實了解由 not only 和 but also 所引導的結構必須完全對等。❞

請看例句：

1. Not only you but also I was surprised to see him there.（不只是你，我也非常驚訝在那兒看到他。）
2. They not only made the rules but also enforced them.（他們不僅訂定那些規則，而且還嚴格執行。）
3. Not only did he invite us to his party, but he also gave us gifts.（他不但邀請我們去參加他的派對，而且還給我們禮物。）

● 秒懂關鍵

❶由 not only 與 but also 所引導的兩個項目雖然在文法上必須對等，但是在語意上卻較著重第二項，因此若用來作為主詞，動詞必須與第二個名詞一致，如 a 句所示。

❷若 not only 和 but also 引導的是子句時，記得句首由 Not only 所引導的子句必須採倒裝形式，而第二個子句則應由簡單連接詞 but 來引導，副詞 also 必須置於靠近動詞的位置，不可置於主詞之前，如 c 句所示。

❸因為 also 不是連接詞，所以可以省略不用；換言之，a、b、c 亦可寫成：

1. Not only you but I was surprised to see him there.
2. They not only made the rules but enforced them.
3. Not only did he invite us to his party, but he gave us gifts.
